i have a good signal at home and have many connections but i need to add another.
they both would receive a 3.5db loss giving which ever a total of 12-14

i need to spilt either a :

1.non hdtv with digital TWC box

or

2.spilt a HDTV with no box both are sub 20" tv. (this one has a very long run as is about 40ft maybe more.


which would see the less and of a diminished signal.

If you end up with 12-14dBmV, take your pick.

cool

If you haven't done this already just give it a try on one then the other?
